Physiology Physiology is the scientific study of function in living systems. This includes how organisms, organ systems, organs, cells, and bio-molecules carry out the chemical or physical functions that exist in a living system.
Physiology is the study of how organisms function. The physi-part of the word comes from a Greek word that is broadly translated as 'natural origin.' The same root is used to form the words physician, physical, and physics. When we think of physics today we think of the study of how matter and energy work, but another way to think about physics is as a study of how nature functions. In that sense, physiology is also a study of how nature functions - in this case, within a living organism.
